I watched this after I finished the manwha, and I enjoyed it, even though a lot of things were changed in order to fit a tv show setting. The original story was about counselling, clients, the fragility of the human mind, trauma, and finding meaning and healing; while the show is about using psychology to aid police investigators and help them solve crimes. It's based on the manwha, but it's not a 100% accurate adaptation of it. The author (Lee, Jong-Bum) did an excellent research work in the manwha to convey a lot of information about psychology, and I felt the show didn't honor that, because again, it's a crime show.
The characters were originally well developed, and their acting was fine. But sometimes Dr. Frost was way too emotional, which didn't felt right. I'm happy they didn't try to force any kind of romance between them, that would have ruin the entire thing. The music was nice because of it's lyrics, I specially liked that background instrumental song with a strong bass and drums, which title I can't find anywhere (if you recognize it please let me you, I really enjoyed that alternative sound).
Among the things I like were how the characters interacted with each other, the plot twists and the suspense. Dr. Frost and Yoon Seong Ah displayed the extreme opposite personalities they were supposed to have. They keep Cheon Sang Won as the father figure for all the counselors and the main antagonist was also well defined.
Something that bothered me was that they gave away key elements of the story too early, thing that were essential in the manwha. I'd have love the see the actual dog from the manwha because of the meaning of it, but in the show they only compare Dr. Frost to it. They also mixed a lot of original stories into each episode, which made me confused at the begging.
Overall it was a great show, if you're into psychological thrillers you would like it.
There were two quotes that highly resonated with me:
"Aren't emotions like water in a river? If you stop it, it'll overflow" - Cheon Sang Won
"Not being able to express emotions is like a punishment. Humans interact by sharing emotions. and confirm each other's identities by doing so" - Yoon Seong Ah
